The invention relates to the manufacture of a tire (10) in a bladderless tire mold (12) that incorporates sealing rings (16, 18, 70) that enable the tire (10) to be easily and quickly installed within the tire mold (12) so that the pressurized gas or fluid used to inflate and vulcanize the tire (10) does not leak around the tire bead sections (44, 46) of the tire (10) and escape into the mold cavity (60). An improved method of mounting the tire (10) into the bladderless tire mold (12) allows the tire (10) to be quickly and easily loaded in and unload from the tire mold (12) without the need of moving any mold parts into or out of the space between the tire bead sections (44, 46).
